what about something more... intrusive? like you could play around the map like you would in single player but other players will try to monitor you through the cameras and stuff, and then once they identify you they try to bring you down?

Idk but it would be a cool extension of the streaming part of the ps4/pc and such if instead of the viewers watching you through a stream they watch you on a camera feed.

I would be extremely annoyed if people kept fucking with me whilst I was trying to complete the single player campaign, I didn't mind it as much in Demon Souls, because I would F'n destroy everyone who tried to mess with me, but I feel like if they did it in this it would be annoying.
